NOTE1: Do not forget to select the switch S1( ) to OFF before performing the connection of gyro.
If the switch S1( ) is set to ON without the correct setting of S2( ) fuses F1 F4( ) may burn out.
When setting the switch S1( ) to ON, following settings must be all completed.
NOTE2: Fuses are F1 F4( ) and are used in each lines of gyro signals and exterior power supply line.
When the fuse has burned out, replace with same type fuse after investigating the cause of burn out.
Fuse is ME51NN-0.5A.
